U.S. Census Bureau Announces the Start of First Major Field Operation
On August 12, the U.S. Census Bureau briefed the media on the launch of address canvassing, the first major field operation of the 2020 Census.
The Address Canvassing Operation serves two purposes:
This operation implements methods to improve and refine the U.S. Census Bureau’s address list in advance of the 2020 Census. The Census Bureau needs the address and physical location of each living quarter in the United States and Puerto Rico to conduct and tabulate the census. An accurate list ensures that residents will be invited to participate in the census and that the census counts residents in the correct location.
In-Office Address Canvassing uses imagery to detect housing change or stability over time throughout the United States and Puerto Rico and to compare the number of housing units on the ground to the number in the Census Bureau’s Master Address File. In-Office Address Canvassing was part of a suite of nationwide in-office methods used by the Census Bureau to maintain and update its address list, including processing of address lists from the US Postal Service and tribal, state, and local governments.
In-Field Address Canvassing, field staff, known as listers, visit specific geographic areas within the Self-Response type of enumeration area (TEA) where in-office methods could not assure a complete and accurate address list. Listers identify every place where people could live or stay, comparing what they see on the ground to the existing census address list and verifying, correcting, or adding address and location information, as appropriate. Listers knock on doors at every structure in order to verify or update information and inquire about additional living quarters in the structure and/or on the property. If the lister does not find anyone at home, they verify or update address information by observation.

The Address Canvasing Operation is part of a suite of processes employed by the Census Bureau to update and validate the address frame for the 2020 Census prior to Census Day:
Each of these programs and processes serves to validate addresses in the Master Address File, correct address locations and provide addresses that may not be included in any of the other address datasets. Taken together, along with in-office address canvassing and in-field address canvassing, this suite of programs and processes provides multiple opportunities for the Census Bureau to develop an accurate address list.
The Census Bureau developed the Block Assessment, Research, and Classification Application (BARCA) for use in conducting In-Office Address Canvassing. BARCA provides reviewers with access to baseline (circa 2010) and current imagery to assess change or stability in housing within each of the 11.1 million census blocks over time. Reviewers also use BARCA to compare the number of housing units visible in current imagery with the number of addresses in the Census Bureau’s address list for each block.
Individual census blocks are classified as:
Blocks that are in active or on-hold status in the Spring 2019 will be sent to in-field address canvassing for resolution.
The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years.
2018 Census Test
The 2018 Census Test supports the goal of the 2020 Census, which is to count everyone once, only once and in the right place.
